Hi! As I replied to you on the other thread, maybe the side faces are not perpendicular to the sheet metal cone faces. Please share the files here. Forum experts can help take a look.

Many thanks!

Your profile is not perpendicular, and the sketch is not fully defined. The left end is vertical, and the right edge is beveled:

I have change the right one vertical.

But i don't know what's missing on the sketch, so its fully defined.

The edges of the plate cannot be vertical, they need to be perpendicular to the top and bottom faces. The missing constraint is what keeps the cross section from moving up and down.

You can revolve to 359 degrees and it will flatten, or you could make the shape with perpendicular faces, rip it, and then revolve cut edges by reusing the base sketch. Please see attached 2022 version.

I can't open it, because i have Inventor 2020 version, and i can't download the most recently version.

I do not know if you can make into a 2020 version indstead?
